There are places that are lovely in summer but truly magical in winter. Time appears to stop at Niagara Falls: water droplets freeze in mid-air. Frozen mist sketches surrealistic landscapes and trees and walls near the vast falls seem to turn to glass. Giant blocks of ice thunder down from 168 feet up. Slip on some good boots and a winter coat and get ready to spend a memorable day reliving moments from the Disney movie Frozen.
